We divide 485851 by 25
We want to divide 485851 by 25.

Going ahead to step 1:
The number 25 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 25

Moving on to step 2:
When dividing 48 by 25, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 25 from 48 and we're left with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 25

Moving on to step 3:
25 can be fit into 235 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 225 from 235 and we're left with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 25

On to step 4:
25 can be fit into 108 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
The remainder is 8 after subtracting 100 from 108.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 25

Moving on to step 5:
If we divide 85 by 25, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1943.0
Subtracting 75 from 85 leaves us with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 25

Step 6:
If we divide 101 by 25, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 19434.0
If we subtract 100 from 101, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
25 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 19434.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 19434.04
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19434.04
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19434.04
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 19434.04, and the remainder is 0.0.
